The topic of this paper is the functional and design characteristics of multifamily (formerly collective) residential buildings created in the post-war period of Modern architecture of Niš. For the post-war period of intensive and mass construction of residential buildings, a time classification of constructed buildings was performed, and they are classified into two categories. The first category includes buildings built in the 1950s, in the period of the „mature“ Modern architecture, which is a continuation of modern architecture of Niš between the two world wars. The second category consists of residential buildings created in the late 1960s and 1970s, in the period of the late (industrial) Modern architecture of Niš. In this paper, two representative examples of residential and commercial buildings from the mentioned periods were selected, both built on the 14. Oktobar square, in the central core of the city of Niš. As typological representatives of the mentioned periodizations of construction, the buildings will be analyzed in the form of two case studies. Key words: Modern architecture in Niš, functionality, design, building, form 1. INTRODUCTION The term "housing" can, in the context of this research, be defined as the elementary and existential need of human action in architecture and the living space in general. This was especially the task of modernizing the cities of former Yugoslavia after the Second World War, which was primarily researched as a topic of optimizing "invested and obtained", all with the aim of designing buildings for „the masses", that is a large number of inhabitants. The processes that were carried out within the socio-political context of socialism by the previous state apparatus and profession, took place as complete initiatives Received September 27, 2020 / Accepted October 30, 2020 Corresponding author: Marjan Petrović Faculty of Civil Engineering and Architecture, University of Niš E-mail: [email protected] © 2020 by University of Niš, Serbia | Creative Commons License: CC BY-NC-ND 178 M. PETROVIĆ with the general ambition of common improvement of the living conditions of citizens. The residential multifamily architecture of Niš in the period between 1945 and 1980 was based on social and humane ideas within the framework of construction, which were guided through the principles of the methodology of design and realization of buildings of that time. The aspiration towards rational, economical and humane housing was materialized through the optimal functionality of the apartments and the reduced architectural form of the buildings with emphasized primary-secondary plasticity of the facade planes. In addition to the above periodization and grouping of buildings in the previous chapter, the buildings of "mature" and "late" Modern architecture of Niš can be put into a certain spatial framework where residential and residential-commercial buildings within the central city core can be generally typologically grouped, in relation to buildings formed on the spacious boulevards, the former outskirts of the city of Niš. A characteristic example of representatives of authentic Niš architecture from the two mentioned periods in one place, on the 14. Oktobar Square, is a residential and business low-rise building from the period of the so-called „mature“ Modern architecture of Niš, built in the mid 1950s, and a high-rise building built twenty years later in the period of the late-industrial Modern architecture, opposite this low-rise building. The mentioned buildings will be analyzed as typological representatives of residential architecture from the mentioned periodizations of construction, in the form of two case studies. In addition to the selected buildings, the systematization of their parts and elements will be performed, all with the aim of objectifying the topic under research. 2. 14. OKTOBAR SQUARE - CITY-PLANNING LAYOUT AND SPATIAL ORGANIZATION OF BUILDINGS One of the characteristic micro- urban city units - squares in Niš is certainly 14. Oktobar square. With its city-planning setting, it leans on one of the mentioned street backbones of the city from the time of "Winter's plan". The formed square represents the beginning of Obrenović Street (formerly Pobeda street) on the south side, which develops from there to the north through the main central part of the city all the way to the Oslobođenje Square, that is to the Fortress. Fig. 1 14. Oktobar square - Schematic representation of the selected buildings (Source: author - based on part of the graphic documentation of PGR Mediana - first phase in Niš) Design and Functional Characteristics of the Multi-Family Housing Architecture… 179 The city-planning layout of the square is an adopted model of the central park area - "islands" with high greenery that simultaneously form a roundabout. The island is mostly "framed" by residential buildings of different heights with commercial premises on the ground floor. On the north side of the square on both sides of Obrenović Street, there are residential buildings from G+3+A to G+5 in the original design, built in the 1960s. The residential buildings have a rectangular base and a double orientation, towards the street and the inner courtyard (Figure 1). As a counterpoint to the longitudinal residential buildings, on the south side of the square there is a complex of residential tall buildings-towers also with business facilities on the ground floor. In this relatively small area, a high population density was achieved because in this case it was the height that was primary in the design process. (Figure 1.) The positioning of residential towers in that place proved to be a good solution, because in addition to a large number of inhabitants, other city-planning parameters were also met. Despite the great height, a sufficient distance from other buildings is provided, respecting the min. H/2 of a taller building, so there is enough insolation, especially on higher floors. Open views were achieved on all four sides, especially towards the central park, as well as towards the complex of the Orthodox Cathedral, which is located near the east side of the square. The only possibly disputable urban parameter is the number of parking spaces, especially from this perspective, but the standards from the period of construction which was in the early 1970s, should be taken into account. At that time, it was also not a practice to build underground garage levels near residential collective buildings, as it is today, almost half a century later. 3. CASE STUDIES 3.1. Case study 1 "Marger" residential and business building on the 14. Oktobar square in Niš The residential and business building "Marger", B1+G+3+A, was designed in the architecture bureau "PROJEKTBIRO" from Belgrade, the author was the architect Mihajlo Mitrović. The design and construction period was 1955/1956. The building in question was designed as a building in a staggered row consisting of four bays. 3.1.1. Architectural-urbanistic structure and form of the building - volumes and facade surfaces The structure of the set volumes at the given location primarily represents a corner single tract on the corner of Obrenović Street and 14. Oktobar Square. By moving the part of the facade plane, that is shifting the part of the west facade towards the interior of the block, seen from the direction of Obrenović Street, four connected residential and residential-business bays with open views in all directions were obtained (Figure 2). 180 M. PETROVIĆ Fig. 2 Analysis of displacement- "staggering" of the part of the facade plane (Source: author) In addition to the disunity of the volume and the movement of the masses, the architectural form-facade composition represents a human-dimensional and discreet play of primary and secondary plasticity, primarily materialized in two levels. At the level of volume-mass and at the level of facade planes. The volume-mass level means the ratio of the basic volumes of the above-ground floors and the volume of the retracted attic in relation to the main western facade plane, as well as the mutual ratio of bay windows - balconies oriented towards the central park and the basic cube of the southern facade. The first level of "plasticity" of buildings includes subtractive openings in parts of the ground floor for the formation of passages to the inner courtyard-atrium, as well as subtraction of basic volumes at the ground level at the corners where accentuated uneven entrances to residential buildings are formed. The next level in the installation of primary-secondary plasticity is the level of facade planes. "Plastic displacements" at this level are primarily characterized by the "full- empty" principle which is presented in the form of the main volumes ratio and openings in them, or walls, given in the form of windows or retracted balconies-loggias. At this level, there is a sub-level of tertiary plasticity that is formed in relation to the primary plane of the facade in the form of protruding frames or retracted parts of the facade around window openings, as well as slight "movements" of certain architectural
